There should be a limit to which species. 

If you are unable to live in (and own) a property as your principal residence for 5 years, and you don’t qualify for a partial exclusion, you can take actions to qualify for a 1031.

If we were to become unable to pay the remaining $40,000, you keep the $35,000, and you keep your house.

If you are still unable to find a local CPA - Feel free to broaden your search by looking for a CPA that works with clients remotely.

The most common shortfalls were:no Canadian transaction processing (so could not collect rent, nor handle invoices/service payments through the tool);did not accommodate a VAT structure, so GST/HST would be problematic;unawareness of Canadian regulations with respect to residential rentals (not a terribly big issue); andsome were unable to correctly accept a Canadian  address w/ postal code.I'm sure they've made some progress or there are new offerings that are more international and less U.S.A. centric.

Reach out to CPA who works with clients remotely - If you are still unable to find a local CPA that matches your needs.

I would definitely like to keep in touch and ask questions if I'm unable to find the answer via online or through books I'm reading.

Same deal, I'm unable to use the 50% appreciation this property has seen.

If they are unable or unwilling to fulfill the duties of the lease/rental agreement, then reach out to the person they listed as an emergency contract and/or their kin.
